We used guides throughout Japan on our trip and Hiroyuki or Yuki spoke the best English. Highly recommend.
Hope you and your wife returned to the States safe and sound. It's my good memory that I took you to the Nebuta Museum and the Seiryuji Temple. I hope you enjoyed the temple with the Great Statue of Buddha, the five-storied pagoda and the dry landscape garden. And you must have really enjoyed the Nebuta parade at night. I'll be looking forward to seeing you again.
